Access Laser CO₂ Lasers

Q: What is a CO2 laser?

CO 2 laser is a type of laser that uses a gas mixture of carbon dioxide (CO 2 ), nitrogen (N 2 ), and helium (He) to produce a high-powered, infrared light beam. This type of laser is commonly used in industrial, medical, and scientific applications.

Q: How does a CO2 laser works?

CO 2 laser is typically created in a sealed glass tube that is filled with the gas mixture and has two mirrors on each end. When an electrical current is passed through the gas mixture, the molecules in the carbon dioxide gas become excited and begin to vibrate. As these molecules return to their normal state, they emit photons, which bounce back and forth between the mirrors, causing the photons to become amplified and producing a highly concentrated beam of light.

Access Laser has a variety of base models, which can be built up and tuned for industry-leading stability, wavelength selection, polarization purity, or other options depending on specifications. The company manufacture CO₂ lasers longwave (9.0 to 11.4µm) and midwave (5.2 to 5.8µm) infrared lasers for R&D, advanced manufacturing, and more. Wavelength Opto-Electronic is the authorised distributor in Singapore.

The L3 is the world’s smallest CO₂ laser with a portable light source that can be battery-powered for field use. The innovative design allows for air-cooled, fan-cooled, or, in laboratory environments when power stability is critical, water-cooled options.

The L4 is a pivotal design for researchers conducting power-sensitive research in the mid and long-wave infrared spectral regimes. The innovative design provides compatibility with the full array of Access Laser enabling technologies. Combining this flexibility with a compact and robust design, grants researchers and original equipment manufacturers an attractive platform.

The L5 is a versatile laser platform, initially designed for highly demanding industrial environments required to mark and code printed circuit boards. However, this affordable system can be adapted for other high-performance applications simply by changing from fan cooling to water cooling.

L15

The L15 is ideally suited for high-volume, design-integrated applications. The economical design allows for competitive pricing and leading performance among similar sealed, RF-excited CO₂ lasers.

AL20

The AL20 was designed for integration into an industrial manufacturing environment. Yet it still provides uncompromised performance with cost-effective reliability. With these traits in mind, the AL20 provides outstanding results when using any of the ALC technologies with fan-cooled stability.

AL30

When your application requires fast processing speeds and high-resolution performance, depend on the AL30 to provide both. With a specially designed resonator, the output is guaranteed to have a M²less than 1.1 and a TEM₀₀ mode. The ability to focus this virtually ideal beam allows the user to obtain the smallest obtainable spot size thus maximizing power density in the final application.

AL50

This is the laser industry’s highest power, true cylindrical waveguide, RF-excited, sealed CO₂ laser. The AL50 is a no-compromise solution for the most demanding applications: from non-stop 24/7 semiconductor manufacturing to leading-edge research and development.

DL500

The DL500 is the world’s first CO₂ laser specifically designed for performing quick, pain-free hard tissue dental surgery. The innovative design allows for air or fan cooling, reducing the dental workstation's weight and size, and making it easy to maneuver in dental offices.
